Also involved in TNFA and inflammatory cytokines, like Interleukin-1, signaling. Following activation of viral RNA sensors, such as RIG- I-like receptors, associates with DDX3X and phosphorylates interferon regulatory factors (IRFs), IRF3 and IRF7, as well as DDX3X. This activity allows subsequent homodimerization and nuclear translocation of the IRF3 leading to transcriptional activation of pro-inflammatory and antiviral genes including IFNB. In order to establish such an antiviral state, IKBKE forms several different complexes whose composition depends on the type of cell and cellular stimuli. Thus, several scaffolding molecules including IPS1/MAVS, TANK, AZI2/NAP1 or TBKBP1/SINTBAD can be recruited to the IKBKE-containing-complexes. Activated by polyubiquitination in response to TNFA and interleukin-1, regulates the NF-kappa-B signaling pathway through, at least, the phosphorylation of CYLD. Phosphorylates inhibitors of NF-kappa-B thus leading to the dissociation of the inhibitor/NF-kappa-B complex and ultimately the degradation of the inhibitor. In addition, is also required for the induction of a subset of ISGs which displays antiviral activity, may be through the phosphorylation of STAT1 at 'Ser-708'. Phosphorylation of STAT1 at 'Ser-708' seems also to promote the assembly and DNA binding of ISGF3 (STAT1:STAT2:IRF9) complexes compared to GAF (STAT1:STAT1) complexes, in this way regulating the balance between type I and type II IFN responses. Protects cells against DNA damage-induced cell death. Also plays an important role in energy balance regulation by sustaining a state of chronic, low-grade inflammation in obesity, wich leads to a negative impact on insulin sensitivity. Phosphorylates AKT1. {ECO:0000269|PubMed:17568778, ECO:0000269|PubMed:18583960, ECO:0000269|PubMed:19153231, ECO:0000269|PubMed:20188669, ECO:0000269|PubMed:21138416, ECO:0000269|PubMed:21464307, ECO:0000269|PubMed:22532683, ECO:0000269|PubMed:23453969, ECO:0000269|PubMed:23478265}. |Pkinase| |Pkinase Tyr| |IkappaB kinase activity| |NF-kappaB-inducing kinase activity| |K48-linked polyubiquitin modification-dependent protein binding| |I-kappaB phosphorylation| |positive regulation of type I interferon-mediated signaling pathway| |positive regulation of lipid storage| |K63-linked polyubiquitin modification-dependent protein binding| |response to interferon-beta| |TRIF-dependent toll-like receptor signaling pathway| |cellular response to virus| |MyD88-independent toll-like receptor signaling pathway| |regulation of type I interferon-mediated signaling pathway| |regulation of lipid storage| |negative regulation of type I interferon production| |positive regulation of cytokine-mediated signaling pathway| |positive regulation of response to cytokine stimulus| |I-kappaB kinase/NF-kappaB signaling| |intrinsic apoptotic signaling pathway in response to DNA damage| |response to type I interferon| |NIK/NF-kappaB signaling| |positive regulation of lipid localization| |protein phosphatase binding| |toll-like receptor signaling pathway| |PML body| |mitochondrial membrane| |regulation of type I interferon production| |pattern recognition receptor signaling pathway| |regulation of lipid localization| |intrinsic apoptotic signaling pathway| |regulation of cytokine-mediated signaling pathway| |peptidyl-serine phosphorylation| |regulation of response to cytokine stimulus| |positive regulation of I-kappaB kinase/NF-kappaB signaling| |peptidyl-serine modification| |endosome membrane| |innate immune response-activating signal transduction| |regulation of I-kappaB kinase/NF-kappaB signaling| |protein kinase activity| |activation of innate immune response| |negative regulation of cytokine production| |response to virus| |apoptotic signaling pathway| |ubiquitin protein ligase binding| |protein homooligomerization| |positive regulation of innate immune response| |positive regulation of response to biotic stimulus| |protein serine/threonine kinase activity| |regulation of innate immune response| |positive regulation of defense response| |positive regulation of multi-organism process| |protein complex oligomerization| |regulation of response to biotic stimulus| |immune response-activating signal transduction| |immune response-regulating signaling pathway| |positive regulation of response to external stimulus| |activation of immune response| |regulation of cytokine production| |viral process| |regulation of defense response| |innate immune response| |cellular response to DNA damage stimulus| |regulation of multi-organism process| |symbiotic process| |interspecies interaction between organisms| |positive regulation of immune response| |peptidyl-amino acid modification| |apoptotic process| |defense response to other organism| |protein phosphorylation| |positive regulation of intracellular signal transduction| |programmed cell death| |cell death| |regulation of response to external stimulus| |response to cytokine| |positive regulation of immune system process| |regulation of immune response| |negative regulation of multicellular organismal process| |phosphorylation| |response to other organism| |response to external biotic stimulus| |response to biotic stimulus| |defense response| |regulation of response to stress| |ATP binding| |protein-containing complex assembly| |regulation of immune system process| |positive regulation of signal transduction| |intracellular signal transduction| |cellular response to stress| |positive regulation of cell communication| |positive regulation of signaling| |regulation of intracellular signal transduction| |protein-containing complex subunit organization| |immune response| \\ === CRISPR Data === No hits were found.
